. Explorations of the United States Coast and Geodetic Survey steamer "Bache" in the western Atlantic, January-March, 1914, under the direction of the United States, Bureau of Fisheries : oceanography. e upper 1,800 meters,on a line running 200 miles southwest fromBermuda. sahnity below the l,00()-meter level is so small that it is doubtfulwhether this was really the case. ^Certainly, temperature suggestsnothing of the kind but just the reverse. The relationship of these profiles to one another may be illustratedfurther by charts of the temperatures and salinities at the 200, 600,1,000, and 1,800 meter levels. At 200 meters salinity was remarkably uniform, the extreme range,except for the cool, fresh water next the coast (station 10158, p. 45),bemg from to only. The temperature range () was also very small, ° to ° over most of the the coast off Chesapeake Bay it was much colder (° at 20 EXPLORATIONS, WESTERN ATLANTIC, STEAMER BACHE, 1914. station 10158); but east of station 10161 the temperature at thislevel was nowhere below 18°. Off the mouth of the Straits of Floridaand off the northeastern slope of the Bahama Bank (station 10210). Fig. 15.—Temperature profile of the upper 1,800 meters, from Florida to a point 200 miles southwest of Bermuda. the 200-meter temperature rose to 20°, and it was even warmer (22°)in the northeast Providence Channel (station 10196). The course ofthe curve of 19° is worth notice, since it shows a tonguelike extension
